Heats Up The Petrol Brush

Benzokosa stalls

When purchasing a petrol cutter, you need to be prepared for the fact that, like in all other similar tools, breakdowns may also occur in it that will require repair.

However, you should not immediately run to the service center and pay a lot of money to the masters who convince you that there is a serious malfunction in the device.

The benzokosa stalls at high revs on gas

Perhaps the most common complaint associated with petrol trimmers is: The petrol trimmer is stalling.

Of course, a rather serious malfunction can also be the reason for this. However, in most cases the situation is much simpler than it seems at first glance.

To cope with such a problem, first of all, try to figure out its causes on your own, because after finding out the cause, it is much easier to deal with the problem, and sometimes it even self-destructs.

In fact, there are many reasons for this when the brushcutter stalls at high speeds.

Another is the presence of faults in the power supply system.

In this case, the petrol brush will stall at idle. A misalignment or improper adjustment of the carburetor can lead to problems with the power system.

The misalignment can be caused by vibrations that occur during the operation of the petrol cutter.

Incorrect adjustment of petrol cutters can be corrected by simply adjusting it in accordance with the requirements specified in the operating instructions.

In addition, sometimes gasoline trimmers can stall due to the fact that the valve located in the gas tank cap is simply clogged or stuck.

To find out, try using a scythe while loosening the gas cap.

If the device works properly in this mode, clean the valve.

Over, the brushcutter can stall due to poor fuel flow to the carburetor.

Why, then, does the device start up, you ask?

The reason for this is that at first the fuel gradually runs into the carburetor and there is enough fuel to operate at increased power.

However, then it is produced and at high revs the engine starts to stall.

As for the carburetor, the problem here may also be that its body is too tight.

The reason that the petrol brush stalls at high speeds on gas may also be air leaks.

This is the possible presence of a place through which air can pass during the heating process of the engine.

Be sure to check the fuel inlet hose, among other things. The problem may be that it is loose or cracked altogether.

These are the main reasons why a petrol brush can stall.

What could have broken

Problems with the petrol brush, due to the fact that this device does not start, are classified in a certain way by service specialists. They highlight faults with the following components of the mechanism:

  • An engine in which the piston and bearings may wear out or fail, crack the crankcase;
  • The fuel supply system, while the filter may be clogged or problems with the carburetor;
  • Mechanical damage to wires, tubes, hoses;
  • Ignition circuit.

Idle

At idle, common reasons for stopping the trimmer are as follows:

  • Dirt, misalignment or incorrectly adjusted carburetor adjustment;
  • Clogged air filter;

  • Reducing the speed of the gearbox when it heats up, which is a consequence of the use of an unsuitable fuel mixture;
  • Clogged throttle;
  • Air ingress into the system;
  • Not enough fuel to operate the petrol cutter.

At high revs

When the scythe stalls at high speeds, this is due to the following problems:

  • Clogging or sticking of the valve located on the gas tank cap;
  • The carburetor is out of alignment under the influence of vibrations arising during the operation of the mechanism;
  • Problems with the circulation of the fuel mixture;
  • Suction of atmospheric air;
  • The fuel intake hose is cracked or loose.

Adjust the carburetor according to the trimmer operating instructions. For adjustment, it is often sufficient to loosen the tightening of its housing. If there are problematic points with the circulation of the fuel mixture, then it can gradually enter the carburetor. After its development, the engine stalls at high speeds.

When heated

The brushcutter often stops when it heats up. At the same time, it starts, works with jerks and gradually stops. This process occurs when the gasoline in the carburetor boils or the damper is installed in a rotary rather than disc type. In the latter case, the part is changed.

It happens that the trimmer heats up if the ignition circuit wire or coil is damaged. In order for the device to start working normally, parts are replaced.

Why does the petrol trimmer stall

A scythe with a gasoline drive is a useful thing for owners of home gardens, lawns, and when the trimmer suddenly stalls, the work to clear the area from grass stops. The device itself is a rather complex mechanism, so there are many different reasons for its breakdown. The most common problems are contained in the operating instructions. You should know the reasons why the trimmer stalls in order to effectively repair the device yourself.

Immediately after wound up

The unit may stall immediately after starting if the carburetor is misaligned or incorrectly adjusted, this causes an uneven fuel supply. The result of this is that the device vibrates distinctly. For troubleshooting, the carburetor is reconfigured, following the instructions for the mechanism.

Also, the engine stops when the fuel supply valve becomes clogged. In such cases, it is sufficient to simply clean it. If the brushcutter first worked, but then immediately stalled, then perhaps the fuel enters the carburetor unit with some difficulty. Weakening the valve helps to resolve the issue, which ensures free circulation of the mixture in the system.

The stoppage can also be caused by air leakage in the presence of mechanical damage to the hose (holes, cracks) that takes the fuel. In this case, add more revolutions to the drive in order to quickly expel air bubbles from the system.

There is no spark and the chainsaw does not pick up speed

The chainsaw stalls when you press the gas due to the fact that no spark. This can happen when there is no good contact between the tip of the candle and the wire (high voltage). However, if this kind of connection works correctly, but there is still no spark, then the whole reason is the ignition unit (electronic). It is important to note that these types of parts cannot be repaired, so they can only be replaced.

Do not forget that by examining the spark plug, you can obtain significant information regarding the breakdown of the chainsaw. Since if its surface is dry, then the reason for this is the cylinder, which is not directly supplied with fuel. That is why you will have to check the entire range of its presentation step by step. If the candle is covered with black soot, this means that the carburetor is not working properly, that is, it either supplies a lot of fuel, or pours oil directly into gasoline.

Silencer as the cause of the saw stalling under load

Here’s another reason why the chainsaw stalls when you press the gas muffler. It is this part that can interfere with the full operation of the tool in cases where it is contaminated directly with exhaust resinous deposits. To do this, you just need to clean it.

The main elements of chainsaws

Before starting to delve into the issues of breakdowns and tool repairs, let’s first figure out what the chainsaw itself consists of. First of all, I would like to note that this tool belongs to the category of technology, the operation of which directly depends directly on the internal combustion engine.

It is also important that chainsaws are equipped with a single cylinder engine, and the work of which is carried out on such a fuel as gasoline. It is worth noting that, despite the similarity with other tools, it does not have a gearbox. And it is replaced by a kind of single-stage chain transmission, through which the movement of the chain itself (saw) is made.

In fact, a chainsaw is a fairly simple design, but this does not prevent it from being reliable, practical and capable of fully providing direct uninterrupted and cyclical operation even in rather difficult conditions. This tool consists of a huge range of certain elements that are vital for its correct and productive work. This is a carburetor, a direct chain tensioner, a tire complete with a chain and other elements.

To make it easier for you to choose, we have compiled for you a rating of chainsaws in terms of reliability.

If you are on a tight budget, read the article about Russian chainsaw manufacturers.

Filling the mixture when the mechanism is running

Direct damage can also be caused by pouring the mixture into a candle at the moment when the mechanism is started. In order to solve this problem, it is necessary to turn out and dry the candle, but remember that it should never be ignited. Excess fuel must be drained through the hole (plug), wait 20-30 minutes, then put it back in place and try to start the tool again.

Why does the chainsaw immediately stall and jam when the gas is pressed

Chainsaws are fairly reliable and simple designs. Therefore, if you properly care for them and handle them based on the manufacturer’s recommendations, then they fail well, very rarely and various kinds of breakdowns are quickly eliminated. But if you are faced with this situation and want to personally repair your tool without resorting to the help of professionals, then delve into the information provided below.

In fact, it is unambiguously and precisely impossible to determine the reason why the instrument does not start or stalls when you press the gas, since there are a lot of factors affecting this. But do not forget that, starting from the fact that the chainsaw is equipped with a simple two-stroke engine, conditions such as lubrication, fuel, spark and air are important for its effective performance.

Therefore, the carburetor is directly involved in the preparation of the fuel-air mixture, the filter cleans the air from dust, the ignition unit and the spark plug create a spark, and there is lubricant in the gasoline.

That is why it is necessary to search for the causes of such a breakdown in a sequential order, starting directly from the simple ones and gradually moving on to the complex ones. And this is an important factor in the correct repair, since the person who, without thinking, begins to analyze the carburetor, brings it to risk. Since this kind the unit must be repaired or adjusted directly in special workshops (read about carburetor adjustment).

Additional Tips

First of all, what you should remember when purchasing this kind of tool is that certain parts of the saw must be replaced with new ones after their service life (passport) has expired. It is for this reason that the instructions should always be at your fingertips, since everything is described in a detailed way there.

These types of details include: sprocket (leading), bus, part of the system (anti-vibration), as well as the chain. Since you should not forget that if this filling is not changed to a new one at the right time, then these worn out parts will negatively affect the rest of the chainsaw. It is for this reason that you frequently check the depth of the direct toothing. Remember that it should not be more than 0.5 mm week.

Diagnostics of filters for petrol cutters

Another reason why the gasoline scythe stalls is the air filter. To eliminate it, try removing the filter and starting the trimmer without it. If possible, then you will have to change the air filter to a new one, or at least blow through and thoroughly clean the old one.

The petrol trimmer may not start if the fuel filter is dirty. This is the next step in our algorithm. Here we check the condition of the filter element and, if necessary, replace it with a new one. When replacing, try not to leave the suction pipe completely without a filter, this is prohibited by any operating instructions. Haste can turn into repairing the engine piston group.

Breather and exhaust port

Often, delicate branded petrol brushes do not start and stall due to a dirty breather. The main function of this element is to equalize the pressure in the gas tank. When this unit becomes clogged, a vacuum is created in the tank, preventing the supply of fuel. You can eliminate the malfunction by cleaning the breather. You can use a regular needle for cleaning.

Normal operation of streamers with internal combustion engines can be disrupted due to dirt entering the exhaust channel or a clogged silencer mesh. There is such a problem on older generation models. The issue can be resolved by traditional cleaning and removal of the anti-spark grid.

Complex reasons for the failure of petrol cutters

If the step-by-step troubleshooting algorithm does not work, and your scythe still does not start or stalls, it is worth inspecting the carburetor and the engine itself. A clogged carburetor can be one of the reasons for erratic tool performance. There are three main problems here:

  • Clogged ducts or nozzles. All this is cleaned by special washes or blown by a powerful jet of compressed air from the compressor. Do not use needles and wires, as the bore may be damaged;
  • Worn carburetor gasket. Exit replacement of a failed gasket;
  • Violation of tightness. To check this indicator, you can use an ordinary household tonometer, replacing it with a suitable pressure gauge. Watch the readings: if they do not change everything is fine, but if the pressure starts to drop, then some part of the carburetor is faulty. We’ll have to find it and replace it with a new one.

If everything is in order with the carburetor, then the petrol trimmer may not start due to wear of the piston group. If chips, scratches or scuffs are found, the piston or cylinder should be replaced. Piston rings are subject to mandatory checks. A small backlash of the piston when rocking the connecting rod indicates that it is time to change the rings. It is best to entrust this procedure to the specialists of the service center.

Why the petrol cutter won’t start troubleshooting

Caring for the personal plot, summer residents periodically encounter the fact that the petrol cutter does not start. There are many reasons for tool failure. For the correct diagnosis of the problem, the owner of a useful unit in the country needs to know the device and the principle of operation of its individual parts.

  • How to start diagnostics of brushcutters
  • Checking the fuel mixture
  • We carry out diagnostics of a candle and a candle channel
  • Diagnostics of filters for petrol cutters
  • Breather and exhaust port
  • Complex reasons for the failure of petrol cutters
  • Rules for the operation and storage of petrol cutters

How to start diagnostics of brushcutters

If the brushcutter does not start or immediately stalls after starting, it is necessary to sequentially check all the main components and assemblies. The verification algorithm is as follows:

  • Fuel tank (fuel quality);
  • Candle and candle channel;
  • Air filter;
  • Fuel filter;
  • Breather;
  • Outlet channel.

These nodes are most often the source of major problems that can be eliminated after a thorough inspection.

We carry out diagnostics of a candle and a candle channel

If the quality of the fuel mixture is not in doubt, and the brushcutter stalls when starting, then a flooded candle may be the cause. Here, for repairs, an ordinary candle wrench is suitable (every motorist probably has) and a spare candle.

  • We unscrew the candle and wipe it;
  • Dry it thoroughly (do not ignite);
  • We drain the excess fuel in the chamber through the spark plug hole and dry it;
  • We clean the old candle from carbon deposits using a file or a lady’s file;
  • We expose a gap with a distance of 1 mm (you can check with any coin);
  • We put everything back in place and try to start the trimmer.

If the candle is working, the socket where it is located is completely dry, and the petrol cutter does not want to start, lubricate the threaded connection with gasoline. It should be slightly damp. No matter how wonderful a spark the candle may give out, there is simply nothing to ignite in a dry chamber.

If the trimmer motor still does not start, you should exclude such a reason as the absence of a spark due to poor contact between the spark plugs and the high-voltage wire. If the connection is good and there is still no spark, most likely your ignition unit has flown. Here it will not be possible to do without a master, since the part is not repaired, but sold as a single unit.
